Introduction
• Managing mobile assets in a hospital is an enormous task
• RTLS is increasingly important strategic capability for hospitals
![Page 6: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ... Providence Health and Services](https://reader031.vdocuments.us/reader031/viewer/2022021900/5b5309e07f8b9add3a8b56bf/html5/thumbnails/6.jpg)
Key Healthcare Requirements
• Mobility – Health care is inherently mobile – few things maintain a
static location • Change
– Hospitals constantly fine-tune their physical plant - RTLS must be able to accommodate this change
• Physical Environment – Clinical requirements can make accessing drop ceilings and
drilling in walls, along with more extensive renovations expensive and time consuming
– Patient care disruption is a major consideration
![Page 7: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ... Providence Health and Services](https://reader031.vdocuments.us/reader031/viewer/2022021900/5b5309e07f8b9add3a8b56bf/html5/thumbnails/7.jpg)
RTLS Comparison Criteria
– Accuracy
– Reliability
– Planning, Deployment and Operational
Concerns
– Cost and Ongoing Maintenance
![Page 8: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ... Providence Health and Services](https://reader031.vdocuments.us/reader031/viewer/2022021900/5b5309e07f8b9add3a8b56bf/html5/thumbnails/8.jpg)
Accuracy
• Knowing location, status and movement of things is what RTLS is all about
• Lessons Learned: – Must provide enterprise-wide coverage – Must offer persistent location accuracy
throughout an organization
![Page 9: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ... Providence Health and Services](https://reader031.vdocuments.us/reader031/viewer/2022021900/5b5309e07f8b9add3a8b56bf/html5/thumbnails/9.jpg)
Reliability
• What ongoing maintenance/upkeep is required to maintain reliable positioning?
• Lessons Learned: – To eliminate ongoing fine tuning by our IT
group, select a technology that is both self-calibrating and self-healing
![Page 10: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ... Providence Health and Services](https://reader031.vdocuments.us/reader031/viewer/2022021900/5b5309e07f8b9add3a8b56bf/html5/thumbnails/10.jpg)
Planning Scope: Have a thorough understanding of exact steps
required to scope, plan and design RTLS
Lessons Learned: • Some vendors “guesstimate” certain portions of the planning
process • Get clear agreement on who’s responsible in the event of
unanticipated costs
Plant: As the hospital physical plant changes what physical and software reconfiguration is required?
Lessons Learned: • Be sure the entire planning and deployment cycle does not need to
be repeated
![Page 11: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ...

Deployment
• Understand actual installation, configuration and testing of the system
• Lessons Learned: – How and where are receivers actually installed?
How many are required? – Get clear understanding and documentation of
deployment time – Confirm location accuracy against requirements
![Page 12: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ...

Costs • There are 3 main components:
– Actual labor, hardware, and software costs – How the system is packaged and sold to the hospital – Ongoing maintenance and support
• Lessons Learned: – Significant cost variable in receiver installation – Receivers require power and network connection – how
connections are made greatly impacts costs – Confirm receiver density required to achieve desired
positioning accuracy

Costs
• Lessons Learned: – Purchase of RTLS can be packaged as a
capital purchase, lease or rental – How RTLS is packaged can greatly
impact future costs and the degree of risk you may assume over the life of the system

Case Study 1: RTLS Initial Goals
• Administrative – Reduce lost, stolen, misplaced equipment – Increase equipment utilization to reduce capital budget – Enhance staff productivity, efficiency and satisfaction
• Clinical – Reduce time searching – Increase patient care time
• Materials Management – Increase efficiency of PM process – Improve equipment request response time

Case Study 1 : KP LAMC: Primary Use Case
• Clinical users search by asset type – Of particular value are clinical asset types
not managed through Materials Management, Central or Biomed (Lifts, Scales, etc.)
• Materials Management users search by specific Asset ID number for preventive maintenance

Case Study 1: LAMC RTLS Comparison
Accuracy • Consistent 1-3 meter
location accuracy throughout the enterprise
• Solution allow applications where tags are to be tracked in boxes, cabinets, closed carts, and other enclosed areas
Reliability • As soon as sensors
plugged in, they begin forming wireless network
• Sensor network organizes automatically and continuously – self-calibrating and self-healing
![Page 22: Evaluating RTLS Technology - rfidjournal.netrfidjournal.net/masterPresentations/live2009/np/exec_strat_429_140... · Evaluating RTLS Technology: ...

Case Study 1: LAMC RTLS Comparison
Planning • Did not require any pre-
installation RF surveys or detailed system design
• Sensors plugged into standard electrical outlets
• As soon as they’re plugged in, they begin forming the wireless network
Ongoing Maintenance • RTLS in operation for over 2
years • Zero IT maintenance
involvement during this time • System maintains positioning
accuracy and high reliability – self-healing, self-calibrating

Case Study 1: Outcomes Estimated Reduction in Staff Time Searching (Per Employee Per Shift) Before RTLS After RTLS Time Savings/EE/Shift
~2.5 Hours < .5 Hour >2 Hours
Time that can now be spent on patient care and equipment PM tasks

Case Study 1: Outcomes
• Capital Equipment Savings – Reduced shrinkage (lost, stolen,
misplaced) – Increased utilization (no idle or hidden
equipment, missing asset alerting, improved PM cycles)
• Savings already in $100’s of thousands annually

Case Study 1: Next Steps
• Establish multidisciplinary team to review pent-up demand for tags (OR, ICU)
• Integration to Materials Management preventive maintenance software
• Missing asset integration to alert Security Dashboard

Summary & Conclusions • Accuracy:
– Must provide enterprise-wide coverage – Must offer persistent location accuracy throughout an organization
• Reliability – Must work reliably in dynamic environments where people and equipment are
constantly on the move and where radio frequency (RF) challenges can be considerable.
• Planning, Deployment and Operational Concerns – Have a thorough understanding of exact steps required to scope, plan and design
RTLS • Cost
– Purchase of RTLS can be packaged as a capital purchase, lease or rental – How RTLS is packaged can greatly impact future costs and the degree of risk you
may assume over the life of the system • Ongoing Maintenance
– Solutions must be easy configure, maintain, update, and reconfigure when required – Selecting a fully managed solution relieves my IT department of critical, but costly
responsibilities

Summary & Conclusions • For maximum clinical and financial impact, solutions must offer:
– Rapid Impact Installation: – Rapid, clean (dust free), minimally invasive (no wiring, minimal patient
room interruption) – Easy retro fit into existing environments and easily accommodate
change
• Pick a vendor vested in your success
• Technology allows us to rethink how we can provide care.
• RTLS allows the enterprise to do more with less
• RTLS allows us to personalize healthcare for our patients
